California Farm Water Coalition: telling thirsty Californians why agriculture needs water, The
The allocation of water for agricultural use in the western United States is currently being called into question. This scrutiny is most keen in California, a state with more than nine million acres of irrigated farmland. ... -
Improving channel maintenance methods for Egypt's irrigation systems
After the construction of the High Aswan Dam in Egypt (1950s), the channel maintenance methods adopted by Egypt's Department of Irrigation included the employment of heavy, inefficient construction equipment that was ... -
Routing flood water through an irrigation delivery system
The Turlock Irrigation District, located in the Central Valley of California, supplies irrigation water to 150,000 acres and electricity to over 60,000 customers. The District's irrigation service area is highly developed, ... -
Canal linings used by the Bureau of Reclamation with emphasis on rehabilitation
Designers, and others interested in water resource development, have strived to improve the cost effectiveness and technical properties of canal liners. Reclamation (the Bureau of Reclamation) has been involved in this ... -
Experience with flexible schedules and automation on pilot projects
Worldwide the on-farm water management restraints created by rigid water supply schedules cause problems of inefficient irrigation and rainfall use, high water tables, lowered production, increased and less convenient ... -
Mapping technology and GIS
Mapping technology, specifically photogrammetry and its related disciplines, has been extensively employed for irrigation and drainage engineering and management applications since becoming a practical tool in the post ... -
Decentralized constant-volume control of irrigation canals
The Saint-Venant equations of open-channel flow were linearized using the Taylor series expansion around an equilibrium condition. A set of linear dynamic equations were obtained for a canal with multiple pools. The ... -
Field manufacture and application of reinforced plastic canal and pipe linings
Unlined canals and ditches seep, erode, and present management problems. Over time concrete lined canals crack and deteriorate. Pipelines and culverts crack, corrode, leak, and function poorly. A problem solution for unlined ... -
GIS and conjunctive use for irrigated agriculture
A microcomputer based geographic Information (GIS) Is presented for decision support in conjunctive use of groundwater and surface water for irrigated agriculture. A powerful, yet low-cost, raster GIS for PC's called IDRISI ... -
Determination of irrigated crop consumptive water use by remote sensing and GIS techniques for river basins
This paper outlines a method for using remote sensed data from Landsat TM satellites and geographic information systems (GISes) to model the evapotranspiration requirements of irrigated cropland within the Cache la Poudre ... -
Putah South Canal remote acoustic water level monitoring and flow measurement
The Putah South Canal (PSC) was constructed as a part of the Solano Project by the U. S. Bureau of Reclamation for the conveyance of water to the agricultural and urban member units of the Solano County Water Agency in ... -
AZSCHED computer software for irrigation scheduling
AriZona irrigation SCHEDuling (AZSCHED) software provides irrigation scheduling information on 15 crops in up to 60 fields, with different planting dates, soil types and irrigation strategies. AZSCHED uses the soil water ... -
How probiotic fertilizers improve irrigation efficiency, buffer salts, and reduce nitrate infiltration into groundwater
Since the advent of chemical fertilizers there has been a loss of humus in most agricultural soils and a diminishing of the vital biological dynamics which were present in less intensive chemical farming. The loss of healthy ... -
Agriculture's impact on water resources in Eastern Europe: Bulgaria, Hungary, and Romania
Irrigation and other agricultural practices have had a profound impact on the environment in Eastern and Central Europe. The focus here is on water resources, the impact of irrigation on the environment, and the impact of ... -
Long-term storage through indirect recharge
The Central Arizona Project is nearing completion and is currently operating in partial capability. Central Arizona finds itself with a plentiful water supply available from the Colorado River but without the physical or ... -
Artificial recharge of groundwater
Since planning for droughts must be done in wet cycles, storing surplus surface water behind dams or in aquifers is essential. Underground storage is enhanced by increasing the infiltration of water into the soil, using ... -
Management of water conservation through irrigation system modernization and rehabilitation
A landmark water conservation agreement became effective in December 1989 between the Metropolitan Water District of Southern California and Imperial Irrigation District to conserve 106,110 acre-feet of water annually ...
